LAMP-STOVE FOR DEN'i'lSTS.

Specification forming part of Letters Patent No. ,@Q%, dated October 16,1866.

To all whom it may concern.-

Be it known that I, S. P. HILDRETH, of Mount Vernon, in the county ofKnox and State of Ohio, have invented a new and useful Improvement inStoves for Dentists; and I do hereby declarethat the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the'same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l is an edge view of the plate that covers the hole in which thevulcanizin g-jacket is placed when said jacket is removed. Fig. 2 is avertical longitudinal section through the line a: 00, Fig. 3. Fig. 3 isa top or plan view of my improved stove.

Similar letters of reference indicate like parts.

My invention has for its object the furnishing a stove forthe use ofdentists, for packing rubber, vulcanizing, 850.; and it consists incombining a jacket for holding the vulcanizingflask with a stove,constructed as hereinafter more fully described.

A is the lamp, which is five inches in diameter, one and a half inchdeep, and has a wick two and a half inches wide, and its tube is two anda half inches in height above the top of the lamp.

B is the body of the stove, which is fourteen inches long, seven incheswide, and two and a half inches deep. The stove is supported on legs 0,of such a length as willraise the stove to the proper height forreceiving the lamp A beneath it. The lamp A is placed beneath theforward end of the stove, and directly above said lamp there is attachedto the bottom of said stove a collar, D, within which enters the top ofthe lamp, as shown.

The bottom of the store within the collar D is perforated for thepassage of the flame of the lamp; and the said bottom within the saidcollar is struck up into the proper shape for directing the air againstthe flame, so as to give a good shape to the flame and insurecombustion. Directly above the perforation for the lamp-flame in the topof the stove is formed a circular hole four and a half inches indiameter. When the stove is not in use as a vulcanizer, this hole maybecovered with the plate E; but when used for vulcanizing, the plate E isremoved and replaced by a jacket, F. This jacket fits into the hole inthe top of the stove, and is. four and a halt inches in height. Theupper edge of this jacket is scalloped and bent inward, as shown in Fig.2. This jacket holds the vulcanizing-flask when the apparatus is usedfor vulcanizing.

To the rear end of the stove B is attached a pipe, G, in the usual way.This pipe is seven inches in height, is made oval, the longer diameterbeing two and a half inches, and the shorter diameter one inch.

H is a piece of glass covering an opening in the front of the stove, toenable the flame of the lamp to be seen and regulated.

The dimensions given are suitable for a twopiece vulcanizer; but th ycan of course be varied to answer the requirements of each case.

I claim as new and desire to secure by Letters Patent- The jacket F, incombination with the body B of the stove, having collar D and pipe G,substantially as described, for the purpose specified.
